Skill

Possibly a glitch, showing a non-playable trooper during an epic mission with duplicated skills.

A skill is a special ability a Trooper gains every level. Those can be weapons, equipments, stat upgrades, special skills or maybe even a vehicle your trooper could use during a battle. A trooper you purchase starts with two skills automatically.

To obtain certain skills the trooper must first reach a certain level. Some other skills may require an equipment slot to use them. A trooper can carry only 3 pieces of equipment into battle at a time.
